Red Ace Squadron

During the installation you can pick where you want the program
to be placed and if you want you can also place a shortcut on the desktop.

In this game you are in World War I and you are in the air force.

The difference between Master of
the Skies The Red Ace and Red Ace Squadron is that the aircraft are a little
bit better. The machine guns are more effective than they are in Master of the
Skies The Red Ace.

In training level 3 you get to take down a few buildings, aircraft and some
anti-aircraft guns with the help of your friends.
The only bad part of the game is that there are only 3 training levels in the
demo and the training levels are easy so I suggest you buy the real game.
